endodontics clinical skills course Flashcards
length of max central incisor
23.3 mm
length of max lateral incisor
22.8mm
length of max canine
26mm
what do we need to make sure when measuring working length
reducible reference point
how do we access central insider
how do we dress access teeth
- temporary
- non settign calcium hydroxide
small pledget of coots wool in chmaber - GIC in access cavity
what does calcium hydroxide do as interim dressing
= maintains disinfected enrviroentmen
what does cotton wool do
makes reaches easier and allows for little expansion
what does coronal flare do
- removes most infected tissue in coronal part
- allows access for irritant solutions as funnel shape is created
- improves access to apical portion
- working length accuracy
- less preparation errors
how are gg organised to remove debris
- mid part of file is doing the work
debris brought to the top to reduce blockages - taper increases more greatly than rotary file
what is classed as dead zone
firth than 2mm form needle tip
what does SX lie use
canal in end vu block 16mm
SX file to advance to canal
what rate of flow is aimed for irrigation
1ml/15 seconds
increasing over 4ml /mintue increases risk fo extrusion
what shoudl be recorded in treatment
what is coronal flare conducted with
GG burs
what is apical preparation conducted with
why is GG burs good for coronal flares
where do we feel a stop with file
apical constriction - feel a stop
what is usually working length
19 mm
at working length what is feel size increased after first file
increased in size by 2 files
master apical fiel - biggest file at apical constriction
the next file used is what of working length
1mm short
what is final finished carried out with
what is the correct filling technique
- file inserted passively to full working length
file cuts dentine as it is withdrawn from canal
how do we check patency
what problems occur with obturation
how do we restore anterior root filled tooth
what material is good to fill anterior root filled tooth
